This example demonstrates how to name figure 3. Core mathematical concepts include the naming and classification of geometric shapes. Using GeoGebra commands such as Textfield, Segment, and OrthogonalLine, the correct figure input can be constructed. Suitable for middle school and above students learning geometric construction.

AI Drawing Prompt Reference

Draw a triangle ABC with three vertices A, B, and C. Start by drawing segment AB, then draw a perpendicular line to AB through point B, and mark the foot of the perpendicular as point Z. Next, draw segments BC and AC, and draw perpendiculars to AC and AB through points C and B, respectively, and mark the feet of the perpendiculars as points F and G. Finally, connect points B and Z, C and G, and A and F to form triangle ABC, and label the angle at A as α.
